Definitions

  • This invention relates to a storage battery, and more particularly it pertains to a heater used with such a storage battery.
  • Electromotive force of a storage battery is produced through a kind of chemical reaction, and therefore it is considerably decreased at a low temperature as in winter due to the fact that the temperature of the storage battery itself, especially the temperature of the electrolyte is decreased under the influence of the low ambient temperature. More specifically, the reaction velocity of the electrolyte depends upon temperature, and especially at low temperatures it is lowered so that the electromotive force is decreased. With the electromotive force at 20 C. as 100, for example, that at C. becomes as low as 50.
  • the technique of embedding a heater element in a battery casing is disadvantageous in that much trouble is experienced in the formation of the battery casing or the battery casing per se must be replaced if the heater element is partly damaged.
  • the latter technique, or the technique of placing the storage battery on a flat heating plate has such drawbacks as that the thermal efficiency is low since heating is effected with respect to the bottom face of the battery only, and that heat loss is great since the heat conduction is effected through the laminated mass so that considerable time as well as high power is required to elevate the temperature of the electrolyte to a desired value.
  • this technique is by no means an effective method of heating a battery.
  • a primary object of this invention is to provide a heater for use with a storage battery, comprising a heater element embedded in a resin, thereby efficiently heating the electrolyte from the peripheral faces of the storage battery body and thus preventing a decrease in electromotive force.

  • FIG. 15 is a sectional view taken along the line C-C of FIG. 14.
  • the reference numeral 1 represents a storage battery body, and 2 a heater accommodated on the storage battery body for the purpose of heating the latter.
  • the heater 2 consists of a face heater element 3 serving as base member impregnated with a synthetic resin 5 and configured into the form of a top open box.
  • the aforementioned face heater element 3 serving as the base member is formed as follows. That is, when heat-resisting wefts 3b and warps 3c are woven into a cloth, a heater wire 3a is woven together with the wefts 3b in a zig-zag manner in the center of the cloth, and also lead wires 3d having substantially the same expansion and contraction ratios as those of the heater wire 3a are woven together with the warps 31: at opposite edges of the cloth.
  • the heater wire 3a is connected with the lead wires 30! to provide a desired capacity.
  • reinforcement member 4 such as a heat-resisting cloth or mat is provided on opposite sides of the face heater element 3 for the purpose of reinforcement.
  • a heat insulator such as glass fibers or the like may be attached to the outer face of the face heater element 3- to prevent heat from being dissipated from the face heater element 3, so that heat loss of the face heater element 3 can be completely prevented. structurally, it is advantageous to dispose the heat insulator outside the reinforcement member and make them integral with each other by the use of resin.
  • Lead wires 6 and 6 such as copper foils or the like connected with the ends of the lead wires 3d provided at the opposite sides of the face heater element 3 are extended as far as the mounting portion of the attachment plug 7 provided on the box-like heater 2.
  • the lead 'wires '6 and 6' are not exposed at the surface of the heater 2 but completely embedded in the heater 2 except for those of their portions which are associated with the mounting portion 7.
  • These lead wires 6 and 6' have their terminating end portions each about mm. in length projecting from the surface of the resin 5, as shown in FIG. 4. This can be achieved by setting the lead wires 6 and 6' in this Way prior to the molding of the resin.
  • the power source attachment plug is attached to those end portions of the lead wires 6 and 6' projecting from the resin surface.
  • the lead wires 6 and 6 can be completely connected with plug inserts 8 by disposing the latter in contact with the exposed portions of the lead wires 6 and '6' and fixing the plug 7 to the heater 2 by locking means such as a bolt and nut.
  • the surface of contact between the heater 2 and the attachment plug 7 is completely sealed with an adhesive agent or the like.
  • the present invention is by no means restricted to such method.
  • a method such as shown in FIGS. 8 and 9 is also conceivable.
  • the heater 2 is composed of an inner casing 10 and outer casing 11 which are formed by molding a resin.
  • the box-like heater 2 is formed by simply adhering the face heater elements as shown in FIG. 6 to the outer bottom surface and opposite outer side surfaces of the inner casing 10 previously, then fitting the outer casing thereon, and thereafter either thermally compressing the whole or adhering them to each other with an adhesive agent.
  • the inner casing 10 be configured in a similar box-like shape to that of the outer casing 11.
  • the inner casing 10 may be formed in a channel shape with side surfaces having no face heater element applied thereon.
  • the heater 2 can be readily produced.
  • such heater can be easily formed of a plate-like thermoplastic material.
  • the face heater element 3 can be easily located in the center of the width of the resin layer, and thus excellent water-resisting property and electrical insulaton can be realized.
  • the heater 2 was configured in boxlike shape, it is also possible that the heater may be formed in a channel like shape in which only the walls having the face heater element 3 embedded therein are present and opposite side walls are absent. Such a configuration leads to rationalization of the manufacturing steps and savings of material.
  • the heater 2 has been described and illustrated as being configured in a box-like or similar shape.
  • the heater 2 is of band-like shape and it can be wrapped on the peripheral surface of the storage battery body 1.
  • the face heater element 3 is sandwiched between two synthetic resin films 13 and then these films are bonded to each other either thermally or with a bonding agent.
  • the resin films 13 are thermo-plastic resin films, so that they may be used for any desired dimensions of storage battery.
  • the face heater element 3 held between the bonded resin films 13 is enclosed in two sheets of cloth 14 and 14', as shown in FIG. 12.
  • the heating ability of the heater 2 can be improved by forming one of the cloth sheets or 14 of a good heat insulating material and the other cloth sheet 14' of a good heat conductor material.
  • the face heater element 3 held between the bonded resin films 13 may be enclosed in the cloth sheets 14 and 14' through a heat insulator 15 provided on one side.
  • a heat insulator 15 provided on one side.
  • Clamping buckle members 16, 16 and 17, 17 are attached to the end portions of the band-like heater 2 formed in the above manner.
  • the heater 2 is wound on the outer periphery of the storage battery body 1 and clamped thereto by means of the members 16, 16' and 17, 17'.
  • band-like heater 2 is advantageous over the aforementioned box-like one because the former can be applied to any dimensions of storage battery.
  • threads each formed by twisting 226 pieces of non-alkaline glass fiber 7 microns in diameter 1.7 times on an average.
  • a white cloth is formed which in turn is subjected to heat treatment at 340 C. for 30 hours thereby burning and removing the binding agent applied to the glass fiber and then gradually cooled. Then the cloth has styrene monomer applied thereon and is afterwards embedded in transparent maleic acidphthalate polyester resin.
  • a parting agent such for example as polyvinyl alcohol.
  • care must be taken to remove cloudiness, stains and the like as by polishing the glass with the parting agent.
  • a predetermined quantity of compound maleic acid phthalate polyester resin (trade name, non-saturated polyester No.
  • styrene is applied on the maleic acid phthalate polyester resin to remove air bubbles.
  • Another glass plate on which is similarly applied maleic acid phthalate polyester resin is quietly placed on the glass fiber cloth in such a manner that the jelled resin is opposed to the cloth and no air bubbles are left. The unit is maintained under a pressure of 1 kg./cm.
  • the transparent member having a heater element embedded therein has as high a translucency (transparency) as 83%, since with the white glass fiber cloth having the luster characteristic of glass fiber being embedded in polyester resin, only the heater wire woven in the glass fiber cloth as part of the wefts is seen.
  • the translucency (transparency) was measured at a wavelength of 600 millimicrons with the aid of a Beckman spectrophotometer.
  • the transparency has not to be so high as the above value but it may be as low as 40% Therefore, the method of producing the transparent member is by no means restricted to that described above, and a variety of modifications is possible.
  • the glass fibers are twisted 1.7 times on an average at intervals of 2.5 em, but they may be twisted 4 times.
  • the method of burning the binding agent applied to the glass fibers is disadvantageous in that the temperature should be above 300 C. to completely remove the binding agent while if the temperature is raised above 400 C. the glass fibers tend to be aged so as to become fragile. Hence, the temperature should be in the range of 300 to 400 C.
  • the use of the heater 2 thus formed makes it possible to heat the storage battery without destroying the features of glass in case the battery casing is formed of glass.
  • the reference numeral 18 denotes a heater, 19 a thermostat casing accommodating a thermostat 21 therein, 20 a power source cord, and 6 and 6' lead wires extending from the heater element 3.
  • the method of treating the thermostat and heater lead wires may be similar to that of mounting the power source plug. That is, lead wires 6 and 6 such as copper foils from the face heater element are extended to the thermostat mounting portion, and about 10 mm. long end portions of these lead wires are taken out of the resin surface. These lead wires, thermostat lead wires and power source cord are connected with each other within the thermostat casing.
  • the heater wire 3a may be formed of either one of a conductive resistance metal wire, carbon fiber, thread having graphite, carbon or the like applied on the surface, etc.
  • the heater embodying the present invention is capable of efliciently heating the electrolyte contained in the storage battery and preventing the electromotive force from dropping due to a temperature decrease of the electrolyte, thereby making it always possible to produce a constant electromotive force.
  • the heater according to the present invention is of simplified construction and is formed independently of the storage battery itself so that if damaged; it can be readily replaced with a new one. This constitutes an advantage in respect of handling. From the foregoing, it will be appreciated that the heater embodying the present invention is not only free from the ditficulties encountered in conventional heaters of this type but possesses also novel features of its own.
  • An electrical heater for a storage battery comprising: a laminated body, said laminated body being in the form of a rectangular box having an open top side whereby a storage battery case may be lowered into said body, said body comprising an inner woven cloth having weft and warp threads of electrically non-conductive material interwoven with an electrically conductive heater wire means, a heat-resistant reinforcing layer of material along the opposite sides of said cloth, lead wire means connected with said heater wire means and extending therefrom to outwardly of said body and forming electrical terminals at a location on an outer surface of said body, an electrical supply plug means having respective contact elements in contact with said terminals.
  • said wire means comprising a first wire means woven in zig-zag fashion together with said weft threads throughout the body of said cloth and a second wire means interwoven with said warp threads only along opposite edges of the cloth, the second wire means being lead wires connecting said first wire means to said terminal means.
